Hot-Chord: A Query Algorithm for Accelerating the Locating of Hot Resources

Chord is a common circular P2P model with high routing efficiency and stable data inquiring. This paper proposes the Hot-Chord algorithm according to the fact that hot resources have occupied the majority of searching in the P2P system. Hot-Chord algorithm constructs an inner chord dynamically by using the nodes which hot resources is locating, to decrease the inquiring space; Nodes join or leave the inner chord adaptively according to the variation of resources searching rate. On the basis of theoretical analysis and experimental simulation, this paper certifies that the Hot-Chord algorithm has not only the better searching efficiency in hot resources inquiring but also the lower the average number of hops in finding resources than the original Chord and some improved algorithms.
